NEW QUESTION # 30
A developer wants to get access to the standard price book in the org while writing a test class that covers an OpportunitylLineltem trigger.
Which method allows access to the price book?
- A. Use Teat.getStandardPricebookId() to get the standard price book 1D.
- B. Use @TestVisible to allow the test method to see the standard price book.
- C. Use Test.loadData() and a static resource to load a standard price book,
- D. Use @IaTest (SeeAllData=true) and delete the existing standard price book,
Answer: A
Explanation:
Option D: Use Test.getStandardPricebookId() to get the standard price book ID.
Correct Answer.
The Test.getStandardPricebookId() method returns the ID of the standard price book, which can be used in test classes without using SeeAllData=true.
This allows the test to access and use the standard price book in a controlled manner.
Using SeeAllData=true is discouraged as it can make tests dependent on org data.
Deleting data in tests can have unintended consequences.
Option B: Use Test.loadData() and a static resource to load a standard price book.
Unnecessary.
There's no need to load a standard price book via Test.loadData() when Test.getStandardPricebookId() is available.
Option C: Use @TestVisible to allow the test method to see the standard price book.
Incorrect Use of @TestVisible.
@TestVisible is used to expose private members to test classes, not to access data.
Conclusion:
The developer should use Test.getStandardPricebookId() to get the standard price book ID, which is Option D.
Reference:
Accessing the Standard Price Book in Tests
Option A: Use @IsTest(SeeAllData=true) and delete the existing standard price book.
Not Best Practice and Risky.

NEW QUESTION # 33
The following code snippet is executed by a Lightning web component in an environment with more than
2,000 lead records:
Which governor limit will likely be exceeded within the Apex transaction?
- A. Total number of records processed as a result of DML statements
- B. Total number of records retrieved by SOQL queries
- C. Total number of SOQL queries issued
- D. Total number of DML statement issued
Answer: B
Explanation:
The code snippet is likely to exceed the governor limit for the total number of records retrieved by SOQL queries. In Salesforce, there is a limit on the total number of records that can be retrieved by SOQL queries in a transaction. This limit helps in preventing the overconsumption of shared resources. If a Lightning web component tries to retrieve more than 50,000 records, it will hit this governor limit1.
The code snippet has a SOQL query inside a for loop, which is a bad practice and should be avoided. The query retrieves all the lead records with the Origin_c field, regardless of whether they are related to the current component or not. This can result in a large number of records being returned, especially if the environment has more than 2,000 lead records. The query also does not use any filters or limits to reduce the number of records. The code then updates the LeadSource field of each record and performs a DML operation inside the loop, which is another bad practice and should be avoided. The DML operation can also trigger other processes, such as workflows, triggers, or validation rules, that can consume more resources and cause other governor limits to be exceeded.
A better way to write the code would be to use a list variable to store the lead records that need to be updated, and use a SOQL query outside the loop with filters and limits to retrieve only the relevant records. Then, iterate over the list and update the LeadSource field of each record. Finally, perform a single DML operation outside the loop to update the list of records. This way, the code will reduce the number of SOQL queries and DML statements, and the number of records retrieved and processed.

NEW QUESTION # 35
Universal Containers has an order system that uses an Order Number to identify an order for customers and service agents. Order records will be imported into Salesforce.
How should the Order Number field be defined in Salesforce?
- A. Direct Lookup
- B. Lookup
- C. Indirect Lockup
- D. External ID and Unique
Answer: D
Explanation:
Why External ID?
The Order Number is used to identify records uniquely, both in Salesforce and in external systems.
Marking it as anExternal IDensures it can be matched or referenced during data imports and integrations.
Why Unique?
Setting the field as Unique ensures that duplicate values are not allowed for the Order Number.
Why Not Other Options?
A: Indirect Lookup: Used for external object relationships, which is not applicable here.
B: Direct Lookup: Not relevant for unique field identification.
D: Lookup: Used for creating relationships, not for identifying unique fields.

NEW QUESTION # 37
What is the result of the following code snippet?
- A. Account Is inserted.
- B. 201 Accounts are Inserted.
- C. Accounts are inserted.
- D. 200 Accounts are inserted.
Answer: D
Explanation:
The code snippet uses a for loop to create a list of 200 Account objects, each with a unique name. Then, it uses the Database.insert method to insert the list of accounts into the database in one DML operation.
The Database.insert method returns a list of Database.SaveResult objects, which contain information about the success or failure of each record insertion. However, the code snippet does not check the results or handle any errors that might occur. Therefore, the result of the code snippet is that 200 accounts are inserted, unless an exception is thrown due to a trigger, validation rule, governor limit, or other reason. References:
